Cornell SimCafe Structures

This SimCafe Structures Learning Track was developed by Dr. Rajesh Bhaskaran at Cornell University in partnership with Ansys. It serves as an e-learning resource to integrate industry-standard simulation tools into courses and provides a resource for supplementary learning outside the classroom. The following courses show how to solve structural problems using Ansys Mechanical. These tutorial-based courses follow the same high-level steps; starting with pre-analysis and ending with verification and validation. The successful completion of these simulation courses will provide a thorough understanding of how to set up a Structural simulation using Ansys Mechanical.
